6. Oil, hydraulic fluids, and coolants are at operating levels
7. Move seats to most forward position
8. Flaps retracted (0°)
9. Control surfaces in neutral position
10. Position scales (min. capacity. 200 kg / 440 lbs) under each tire
11. Record weights of individual scales
12. Level the aircraft
13. Record weights of individual scales
14. Calculate empty weight
3.6 Determination of CG
1. Drop a plumb bob tangent to the
wing
‟
s
leading edge, (in the un-tapered section of the wing, at about one meter (~
40”) from the root) trace a reference mark on floor
2. Repeat operation on other half-wing
3. Connect the two reference marks with a taut line
4. Measure distances between reference line and landing gear wheel axles
5. Recorded data allows determination of C.G. location and
aircraft‟s
moment (see following table)
